China Circulation Magazine published the "China Cardiovascular disease Report 2016", which showed that the mortality rate of cardiovascular disease was the highest amongst total deaths in China, even higher than cancer. The mortality rates of cardiovascular disease are 45.0% in rural areas and 42.6% in urban areas. Overall, the prevalence rate and mortality of cardiovascular disease in China are still in the rising stage, and with the obvious prevalence of CV risk factors in China, CV disease is expected to continue growing rapidly in the next 10 years.

According to the report, the number of cardiovascular disease patients was estimated to be 290 million, including 13 million with stroke, 11 million with coronary heart disease, 4.5 million with heart failure, 5 million with pulmonary heart disease, 2.5 million with rheumatic heart disease, 2 million with congenital heart disease and 270 million with hypertension.

The report said that in 2015, the mortality rate of cardiovascular disease was 298.42 /100,000 in rural areas (144.79 / 100,000 for heart disease and 153.63 / 100,000 for cerebrovascular disease) and 264.84 /100,000 in urban areas (136.61/ 100,000 for heart disease and 128.23 / 100,000 for cerebrovascular disease).

Cerebrovascular disease:

The mortality rate of cerebrovascular disease exceeds that of heart disease, and according to the national census data, there were 853,600 urban residents and 1,034,900 rural residents who died from cerebrovascular disease in 2015.

According to the Statistics Yearbook of National Health and Family Planning Commission (NHFPC), the mortality rate of cerebral hemorrhage was higher than that of cerebral infarction in 2015, with 52.09/100,000 vs. 41.82/100,000 in urban area and 72.26/100,000 vs. 46.99/100,000 in rural areas.

Coronary heart disease:

According to NHFPC's Statistics Yearbook, the mortality rate of coronary heart disease was around 110/100,000 in 2015, with slightly higher rates in rural areas. This mortality rate was slightly higher than the rates in 2014 (110.5/100,000 in urban and 105.37/100,000 in rural).

According to this commission's PCI network data, there were total of 56,753 interventional therapies conducted for the treatment of coronary heart disease in 2015. This calculates to around 427/1,000,000 people in China who were treated with PCI. The average number of stents remained at around 1.5/person.

The annual volume of coronary artery bypass grafting (CABG) is around 40,000 cases, and is increasing at a rate of around 10% each year. Around 60% of China's pure CABG is carried out without cardiopulmonary bypass, whereas in Western countries, this is around 20%.

Arrhythmia

According to the NHFPC's online registration system, there were approximately 65,697 cases of pacemaker implantation in 2015, which increased by 9.98% since 2014. And there was no significant change in pacemaker indications compared with 2014: Sick Sinus syndrome accounted for 51.1% and atrioventricular block accounted for 39.8%. Dual chamber pacemaker accounted for nearly 69%.

Implantable cardioverter defibrillator (ICD) also showed an increasing trend with an 18.3% increase from 2014, and there were 2,759 cases of ICD implantations in 2015. Single chamber ICD accounted for 67.1% with the rest being dual chamber. 58% of ICD implantations were for secondary prevention.

Cardiac resynchronization therapy (CRT) also showed an increasing trend with an 8.4% increase from 2014, with 2,986 implants in 2015. CRT-D accounted for 57% and CRT-P accounted for 45%.

There were also 1111,000 cases of catheter ablation in 2015, with an annual growth rate of around 13.5%~17.5% since 2010. (Sources: Xinhua and Medlive.cn)
